Well done "Ozzie", that lot is TRULY MODEL ENGINEERING', you are a man in my
club, " make it" dont buy it, i also "never" buy anything if i can make it.
Many years ago when i worked in DONCASTER plant an old guyi was sent to work
with, who was also a model engineer told me off when i said i was going to send for some castings for an engine i was building,(just starting),,dont make them "buggers" any richer
than they are lad,get off your backside and make em! ! .
after much discusing how, i had a go,did as he said beged borrowed and stole some scrap
and got stuck in, as he said..
Well i finnished the loco,Bantam Cock, still got it, (but it needs a new boiler), if the good lord grants me enough time i will make one.
KEEP UP THE GOOD WORK OZZIE

Sorry, this is going back a bit. I have always screwed crossheads on to piston rods, counterbore the crosshead boss so that the thread is not showing, then pin with taper pin or what have you. I leave the crosshead guide bar surfaces oversize and then set the rod up on a veeblock to machine them to 10 thou undersize, they are then in line with the rod. On assembly a 10 thou bronze shim is fitted each side turned over each end to that it is held in place. If it ever wears out, which I doubt, if past experience is anything to go by just fit new shims. I usually set the length at the piston end, screwed, loctited, and a screw fitted half in rod, half in piston. Excellent work, regards Ian
